When I extend Video Node, I don't want my extended node to process any key pressings but "play", but when I write onKeyEvent() for my extended node -- this function isn't called at all, even if I just write this:

function onKeyEvent(key as string, press as boolean) as boolean
       print key
       print press
       return false
end function

it prints nothing and handles every key pressing for me. What can I do to fix it?

That is because you are returning false.

The onKeyEvent() function must return true if the XML component handled the event, or false if it did not handle the event. Returning false allows the event to continue bubbling up the focus chain so that ancestors of the XML component can handle the event.

After upgrading to the last firmware I'm having another strange problem . I'm setting an interface field to be an associative array. In the brightscript thread I can see my whole object, (it's an object that contains key, value pairs for strings and for booleans), but when I try to see it in the scene graph script

BrightScript Debugger> ? m.top.data.localStationData
<Component: roAssociativeArray> =
{

This is all that I get, roku as well as the debugger freezes. I am 100 % that my associative array contains some data (key, value pairs) . What can cause this problem and why I am not seeing the whole output ? Even if the associative array would be empty I should still see <Component: roAssociativeArray> = {}, right ?

I have a component that extends the row list component.I'm using this component in many places. The attributes are set in the init function, and i was overriding them in the brightscript thread which worked fine until firmware version 7.2.0 build 144-04 was installed on my device. Now it seems that i can't change the row list attributes after they have been set in the init function.

For example in the brightscript thread if i make something like this . . . grid = mainScene.createChild("myComponent") - where myComponent extends rowlist
grid.rowHeights = getRowHeights()
grid.rowItemHeight = getRowItemSize()
I should be able to change the attributes, right ? This worked fine prior to the mentioned firmware version. Can you help me out with this ?

@dacian_roman23 - What firmware version and build +(and what device model number) are you testing on ?

- Joel

[dacian_roman23]

Hi Joel ..

The firmware version is 7.2.0 build 4065-04, and the model is 4210X - Roku 2

[RokuJoel]

Hi Dacian, the issue should be fixed in the next build-release. No idea when that will happen, but hopefully soon.

BUG REPORT
I've noticed some weird things when working with a partial screen video and with video transitions to roku billing. Device is an Insignia Roku TV:

1) The bufferingbar and retrievingbar are either hidden or are displayed in the location where they would be for a full screen video (on top of my other components). This is annoying.

2) When i hide the screen containing this preview video, to get a user's partial billing info, instead of flashing black between screens like it typically does, it flashes black except for a still frame of the video (in the position where the video was). This looks fairly janky. I've also tested with a full screen video - same result.

3) MOST TROUBLING: the same video still frame will still show up in transitions between screens of production applications. It seems that one of Roku's biggest concerns with the SDK is crossover between applications - somehow the video still frame is not getting removed from the buffer memory. It stays this way until I restart the device. One example is Pandora. Upon launching it, I see the pandora splash screen, then where it usually flashes black for a split second, i instead see a flash of the stillframe from my video.

Is there some workaround to force delete this image? I'd like to use a partial screen video for a production app.

Here is the general setup of my screen (I added my own "loading" message since the normal one is not displayed on the partial video):

<children>
<Group
	id="VideoGroup"
	translation="[740, 100]"
	>
	<Video
		id="VideoPlayer"
		width="1110"
		height="624"
		/>
	<Label
		id="VideoLabel"
		height="624"
		width="1110"
		text = "Loading..."
		horizAlign = "center"
		vertAlign = "center"
		/>
</Group>
</children>

Any news for the fixes in the 7.2 release ?
